Cleaning down the side of the seats-

[Montjeu]

That's given me an idea, something this could be really cool for hard to reach interior:

The trouble with those little air canisters is that they just blow the muck somewhere else. That's fine for crumbs etc in your keyboard but in the confines of a car you are likely to simply blow the bits to somewhere even more inaccessible!

I like the Bic biro nozzle idea though

Yep, just disturbs the dirt oc but they're reasonably powerful so will move it out of the crevices. Roof down doors open blast. Vacuum handy to pick up disturbed particles. Having used at work I reckon it would be pretty effective, I'm going to give it a shot !
